Theharvester 4binder of which I illustrate a., portoiiisiof theVOrdinary wellknown. cori,-

struction and need not tliereforebe described in detail except to saythat its bull wheel is designated by 1, its deck by 2 andits frame by 3;and that bundlesof grain vare kicked down and oii. the deck 2 ign-theusualfinaii' ner.

Among other elements my novel shocker comprisesa malin frame 4appropriatelyconnected at itsmiiinerl enditovthe frame 3 of theJharvester binder and. supported adjacent to its outer end by'a'casterwhe-el 4?; The. frame 4 is of open fori/n and `is made upv of innerandjouter longitudinal angle irons 5 and 6 and front-and rear cross bars'7 and 8. ;On its outer side bar 6 the framev 4 is provided with alateral'bracket 9 and superimposed onv and tiri-ed to said bracket is aljournal bearing 10, Figure 4. On its inner longitudinal rbar 5 theframe 4 lis pro-y H vided with lateral brackets 11,- and journal-ed insaid brackets 11 isa longitudinal .shaft- 12, equipped at 13 with amiter. gear and at 14 with a sprocket gear, the latter being connectedby a sprocket belt 15, Figure; l, with a sprocket gear'lcarried by theframe 2, and designed to be connected'by a pitnian 17 appropriatelyconnected tothe mechanism of the harvester binder whereby the mechanismof the shocker vwill be vdriven from the harvester binder. Y

Journaled in the bearing 10 on the bracket 9 and also in a bearing 18 onthe inner longitudinal bar 5' of the frame 4 is a transverse shaft 19fixed at one end toa miter gear 2O and having Xed on its opposite end acrank arm 21,V Figure V2. The miter'gear 2O is meshed with the'mitergear 13. and hence it follows that the shaft 19 will be rotated from theharvester-binder through-the driv-` ing connection described.

Arranged above the frame 4 is a cradle 22 which isV preferably formedof. sheet metal,v closed at its rearward endby a swing ingk gate 23 andis'open at its forward end. rlhe said cradle 22 is connected with therear` bar 8 of the frame 4 by a -bracket 24 fixed to the cradle andtheframe bar.

' Located in rear and in spaced relation to the shaft -19 isa transverserock` shaft 25 which is journaled inbearings 261011 the longitudinalbars 5 and (lof the frame 4. The

outer endof the said' shaft 25 is arranged Figure 7.

icc l The rock shaft 25 is provided at 29, Figure 13, with a crank, andpivotally connected at 30 to the said crank is a curvilinear link 31 toone end of which is connected a retractile spring 32 the other end ofwhich is connected to a threaded rod 33 which extends through theforward bar 7 of frame 4 in a loose manner and is equipped in front ofsaid bar 7 with a nut 34 for regulating the tension of the spring. Anarm 35 is fixed to the rock shaft 25 and is arranged to swing in alongitudinal vertical plane, and the spring 32 and 'its connectionsserve to cushion the upward and forward move ment of the said arm 35 andalso serve after the arm 35 has passed a certain point in its downwardand rearward movement to suddenly and. sharply complete the lattermovement of the arm with a view to better releasing the shock which isdeposited on the ground as hereinafter described.

The before mentioned bracket 9, Figures 3, 5, 10 and 11, is preferablyformed of steel and is provided with an upwardly and rear-V wardlyextending arm 40 on which is a beveled head 41. The ksaid head 41 'isdesigned to be engaged by a pivoted latch 42 on the arm 35, the saidlatch 42 being backed by aspring strip 43 and beingprovided with an arm44 associated with the arm 35 to limit the movement 'of the latch 42against the action of the spring strip 43. 1t will also be seen byreference to Figure 2 that the arm 35 is provided with an arcuate vgroove 45.

Loosely mounted on the rock shaft 25 and arranged at the outer side ofthe arm 35 is a swinging mover 46 for swinging the arm 35. The saidmover 46, Figure 10, is connected by a pitman 47 with the crank arm 21on the forward transverse shaft 19. The said arm mover 46 is providedwith a step 48 in communication with a groove 7 Figure 10. andis alsoprovided with a shallow step 49 forward of the groove 47. The rear wallof the groove 47 is square but the forward wall thereof is cam shaped atits inner side as designated by 50 in Figure 6.

Pivoted or fulcrumed at 51 on the forward side of the arm 35 is a lever52 having at itslower end a gudgeon or anti-friction roller 53. rl`hesaid lever 52 is arranged toV swing transversely of the shocker so as tomove the gudgeon 53 from the groove 47 of the mover 46 into the arcuategroove 45 of the lever 35 and vice versa.

Journaled in the outer end portion of the arm 35 and extendingtransversely ofthe shocker is a rock shaft 60. r1`he said rock shaft 60is movable with the arm 35 from the position shown in Figure 7 to theposition shown in Figure 3 and vice versa. Fixed to the inner end of therock shaft 60 is a head 61, Figures 6 and 7. and fixed to the outer endof the rock shaft 60 is a 60 and the fixed gear 27, the shaft 6() willbe turned about its axis when the arm 35 is sii/ung rearwardly anddownwardly and also when said arm 35 is swung upwardly and forwardly.

As shown in Figure 7 a sleeve 65 is arranged in and extends inwardlyfrom the arm 35, said sleeve 65 abutting at one end against the head 61and at its opposite end against a collar 66 that is fixed on the shaft-60 and is interposed between the arm 35 and the sprocket gear 62. Saidsleeve 65 is fixed to the arm 35 and receives the roch: shaft 60 and isprovided at 67 with a xed collar on which is a lug 68, Figures 8, 9, 15and 16.

The sleeve 65 is loosely surrounded by a sleeve 6) which is movable inthe direction of its length. Said sleeve 69 is flanged at its outer endas designated by 70 and is loosely arranged in a slidable member 71connected by a pitman 72 with the upper arm of the lever 52.

As before described the head 61 is fixed to the inn-er end of the rockshaft 60. Said head 61 is provided at its inner end with an L-shapedextension 73 and it is also provided with a rectangular opening 61X,Figure 7. 1n the said opening 61X is arranged a lever arm 74 which isfixed to a rock shaft 7 5 to which is fixed one of the bundle graspingarms 76, said arm. 76 being arranged exterior of and alongside the head61 as shown in Fig. 2. The lever arm 74 is connected by .a link 77 withthe sleeve 69 and also connected by retractile spring 78 with theextension 73 of the head 61. At its heel end the arm 76 is provided witha .spur gear 79 meshed with a spur gear 8O on a complementary bundlegrasping arm 81 which latter is pivoted at 82 to the head 61. As bestshown in Figures 7, 8 and 16 the head 61 is provided with a beveledlatch 90 for cooperation with the lever arm 74. the latch beingpreferably L-shaped and movable transversely of the head 61 under theaction of a spring strip 91 disposed at one .side of thehead 61. YVhenthe latch 90 is in the position shown in Figure 8, the lever 74 willmanifestly be secured to'hold the arms 76 and 81 in closed position.Whenphowever, the shaft 60 is turned together with the head 61, an arm92 on the latch 90 will abut against the lug 68 on the collar 67 withthe result that the latch 90 will be moved .against the naction ofv thespring 91 and the lever arm :4 will be released ifljom.
